当我打印 studentForm 时,值是正确的,但信息为空。这有什么问题?
StudentForm studentForm = (StudentForm) form;
StudentStructure info = studentForm.getStudent();
StudentDaoFactory.getDaoFactory().getStudentDao().insert(info);
这是学生表格
package com.getcare.crud.web;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import net.sf.hibernate.mapping.Collection;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import com.getcare.crud.remote.StudentContactInfoStructure;
import com.getcare.crud.remote.StudentStructure;
public class StudentForm extends ActionForm{
private static final long serialVersionUID = 1L;
private StudentStructure student = new StudentStructure();
private StudentContactInfoStructure studentContact = new StudentContactInfoStructure();
public void setId(int id){
this.student.setId(id);
this.studentContact.setId(id);
}
public void setStudentid(int studentid) {
studentContact.setId(student.getId());
studentContact.setStudentid(studentid);
}
public void setFirstName(String firstName) {
student.setFirstName(firstName);
}
public void setMiddleName(String middleName) {
student.setMiddleName(middleName);
}
public void setLastName(String lastName) {
student.setLastName(lastName);
}
public void setGender(String gender) {
student.setGender(gender);
}
public void setBirthdate(String birthdate) {
student.setBirthdate(birthdate);
}
public void setCourse(String course) {
student.setCourse(course);
}
public Integer getPhone(){
return studentContact.getPhone();
}
public void setPhone(Integer phone){
student.setPhone(phone);
studentContact.setPhone(phone);
}
public String getAddress(){
return studentContact.getAddress();
}
public void setAddress(String address){

student.setAddress(address);
}
public void setClassCode(Integer classCode) {
student.setClassCode(classCode);
}
public void setStudents(ArrayList students) {
student.setStudents(students);
}
public void setStudentContacts(ArrayList studentContacts) {
studentContact.setStudentContacts(studentContacts);
}
public void setStudentContact(StudentContactInfoStructure studentContact) {
studentContact.setContact(studentContact);
}
public void setStudent(StudentStructure student) {
student.setStudent(student);
}
public int getId() {
return student.getId();
}
public Integer getStudentid() {
return studentContact.getId();
}
public String getFirstName() {
return student.getFirstName();
}
public String getMiddleName() {
return student.getMiddleName();
}
public String getLastName() {
return student.getLastName();
}
public String getGender() {
return student.getGender();
}
public String getBirthdate() {
return student.getBirthdate();
}
public String getCourse() {
return student.getCourse();
}
public Integer getClassCode(){
return student.getClassCode();
}
public ArrayList getStudents() {
return student.getStudents();
}
public ArrayList getStudentContacts() {
return studentContact.getStudentContacts();
}
public StudentContactInfoStructure getStudentContact() {
return studentContact.getContact();
}
public StudentStructure getStudent() {
return student.getStudent();
}
@Override
public void reset(ActionMapping mapping, HttpServletRequest request) {
super.reset(mapping, request);
// setId(0);
setFirstName(null);
setLastName(null);
setMiddleName(null);
setGender(null);
setBirthdate(null);
setCourse(null);
setPhone(null);

setClassCode(null);
}
}
然后是 StudentStructure
package com.getcare.crud.remote;
import java.io.Serializable;
import java.util.ArrayList;
import com.getcare.remote.Structure;
/**

public StudentStructure getStudent() {
return student;
}
public void setStudent(StudentStructure student) {
this.student = student;
}
public ArrayList getStudents() {
return students;
}
public void setStudents(ArrayList arrayList) {
this.students = arrayList;
}
/**

*/
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
/**

public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {

}

public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
/**

public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
/**

public String getBirthdate() {
return birthdate;
}
public void setBirthdate(String birthdate) {
this.birthdate = birthdate;
}
/**

public String getCourse() {
return course;
}
public void setCourse(String course) {
this.course = course;
}
// /**

public Integer getPhone(){
return phone;
}
public void setPhone(Integer phone){
this.phone = phone;
// this.contact.setPhone(phone);
}
// /**

public String getAddress(){
return address;
}
public void setAddress(String address){

}

public Integer getClassCode(){
return classCode;
}
public void setClassCode(Integer classCode) {
this.classCode = classCode;
}
// public StudentStructure safeClone() {
// StudentStructure newInstance = new StudentStructure();

// return newInstance;
// }
}
和 StudentContactInfoStructure
package com.getcare.crud.remote;
import java.io.Serializable;
import java.util.ArrayList;
import com.getcare.remote.Structure;
/**
*

*

public class StudentContactInfoStructure {
private Integer id, phone,studentid;
private String address;
private ArrayList studentContacts;
private StudentContactInfoStructure contact = new StudentContactInfoStructure();
public StudentContactInfoStructure getContact() {
return contact;
}
public void setContact(StudentContactInfoStructure contact) {
this.contact = contact;
}
public ArrayList getStudentContacts() {
return studentContacts;
}
public void setStudentContacts(ArrayList studentContact) {
this.studentContacts = studentContact;
}
/**
* @hibernate.id generator-class="sequence"
* @hibernate.generator-param name="sequence" value="studentcontact_id_seq"
*/
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
/**
* @hibernate.property
*
*/
public Integer getPhone(){
return phone;
}
public void setPhone(Integer phone){
this.phone = phone;
}
/**

*
*/
public String getAddress(){
return address;
}
public void setAddress(String address){
this.address = address;
}
/**

*/
public Integer getStudentid(){
return studentid;
}
public void setStudentid(Integer studentid){
this.studentid = studentid;
}
}
我不知道我会修改什么。:D 谢谢
